4 Claims.

My invention relates to a toy object having a waddling motion simulatingthe motion of a duck. Among the purposes and objects are to provide thefollowing:

A simple cam motion operated by the wheels on which the object iscarried when pulled along a plane surface such as a floor to cause awaddling or tilting and swinging motion simulating the waddling of aduck.

A plane oblique end cam and means for revolving the cam to cause aWaddling motion of the object moved by the cam.

An object supported, in part, on a revolving cam shaft in which theobject has an aperture which is countersunk to provide a point bearingto compensate for the tilting swinging motion of the object.

A toy object having a part with parallel sides to engage the fiatoblique end surface of a cam to cause the object to tilt when the cam isrevolved.

I accomplish these and other objects by the construction hereindescribed and shown in the drawings forming a part hereof in which:

Fig. l is a top perspective view.

Fig. 2 is a fragmentary perspective view of the cam and cam shaft axle.

Fig. 3 is a front perspective view showing the tilting and the swingingmotion of the object in broken lines.

Fig. 4 is a top perspective view of a modification.

Fig. 5 is a cross sectional view of the modification shown in Fig. 4,taken on the vertical centerline of the cam shaft axle.

Similar reference characters refer to similar parts throughout theseveral views of the drawings and in the specifications.

General description 1am aware that toys having objects made to move by acam or crank operated from the axle on which the toy object is supportedare not new. The toy object may swing or tilt but not waddle. Bywaddling, as the word is used in this disclosure, I mean the combinedmotion of tilting and swinging as, for example, the motion of a duckwhile waddllng or walking. The figure, when drawn along the floor,simulates the motion of a waddling duck. The cam faces produces anatural motion without jerking or having the appearance of mechanicalmovement.

The figure may be a plane flat board, or plywood, or plastic, onto whichthe details of a picture of the object may be secured or printed, or

2 the figure may be molded to the shape of the object it is intended tosimulate.

In the specifications, I have described in precise detail a preferredform of my invention so that the construction may be more easilyunderstood by those skilled in the art to whichthis invention pertains.The construction may be modified in many respects without departing fromthe principles underlying my invention. I have not attempted to show allpossible modifications which may fall within the scope of the claimswhich set forth my invention. The preciseness of the specifications isnot intended to limit the scope of my patent.

Specifications Referring to the drawings, particularly to Figs. 1, 2 and3, I have shown the object I having the profile of a duck mounted at therear on the axle 2 which passes through the aperture 3. Cams #1 and 5,one on each side of the parallel side surfaces of the figure, have endfaces which engage the antifriction washers 6 and l which rotatablyengage the object at each side as at 8 so that the cams may freelyrevolve on the axis ID with the axle 2 to which the cams are secured.The oblique plane end surface of each cam is spaced parallel to theoblique plane end surface of the other cam and at a distance apart sothat the parallel sides of the object and the antifriction washers maymove between the end cam surfaces as the cams are revolved by the axle.

The wheels [2 and I3 secured to the ends of the axle provide suflicienttraction on the floor over which they are rolled to rotate the cams andthus cause the object to waddle.

The front end of the object is preferably provided with the eye 14 whichloosely fits over and slides on the guide bar I5 which may be tiltablymounted on the side frames l6 and Il, the rear ends of which are securedto the bearings l9 and 20 which are apertured to receive the axle 2.

The front ends 2| and 22 of the side frames are secured to the king pinbearing 23, the aperture 24 of which receives the king pin 25 which alsoengages the tongue piece 26 to which the front axle 21' is secured. Thefront wheels 28 and 29 are bored to freely revolve on the ends of theaxle and the tongue piece is notched at 30 to receive the tongue 3|which is swingingly. secured therein at one end, by the pin 32. Theopposite free end 33 of the tongue is provided with the handle 3d fordrawing the device along the floor or other surface.

In the modification shown in Figs. 4 and 5, I

I have shown the figure l as conforming to the shape of a duck and beingprovided with a center boss la which is provided with fiat plane sides35 and 36 which are a substitute for the fiat plane surfaces of Fig. 1in engaging the end surfaces of the cams to cause the figure to waddle.

The sides 3'! and 38 of the figure may be notched or cut out at 39 and40 to clear the axle 2. The object may be hollow and the boss la maydepend from the inner top interior at the center.

Refering particularly to Fig. 3 of the drawings, I have shown thetilting angle A as represented by the broken lines of extreme travel ona vertical plane and the swinging angle as B; the extremes of travel ona horizontal plane are shown by broken lines.

To prevent binding and yet permit substantially no lost motion in theaperture 3, I have countersunk the sides as at 0 and Id so that theobject rests on aknife edge annulus rather than a cylindrical bore.

While the waddling motion caused by the rotation of the cams seems bestsuited to the motion of a duck, other objects may be given a similarmotion by the cams and structure herein disclosed.

Having thus described a preferred embodiment of my invention, what Iclaim as new and desire to secure by Letters Patents is set forth in thefollowing claims.

I claim:

1; In a, toy figure comprising a wheeled frame and a figure movable inrelation to the frame, said frame having wheels on which the toy figureis moved along, the wheels being secured to axle, supporting the figureand provided with cams secured to rotate with the wheels and providedwithoblique cam faces for engaging substantially parallel faces on saidfigure to tiltand swing the figure in relation to the frame and atrans.-

versely disposed guide secured to the. frame for and; a. figure. movablein relation to the frame,

said'frame having wheels at the front and rear onwhich the toy figure ismoved along, the rear wheels being secured to an axle supporting therear of said figure and provided with cams s'ecured to rotate, with therear wheels and pro.-

vided with oblique cam faces for engaging substantially parallel faceson said figure to tilt and swing the figure in relation to the frame andmeans on said frame supporting the front end of said figure to permitthe front end to swing from side to side in relation to said frame whiletilting to impart a waddling motion to said figure.

3. In a, toy figure comprising a wheeled frame and a figure movable inrelation to the frame, said frame having wheels at the front and rear onwhich the toy figure is moved along, the rear wheels being secured to anaxle supporting the'rear of said figure and provided with cams securedto rotate with the rear wheels and provided with oblique cam faces forengaging substantially parallel faces on said figure to tilt and swingthe figure in relation to the frame, means on said frame supporting thefront end of said figure to permit the front end to swing from side toside in relation to said frame while tilting to impart a Waddling motionto said figure, said figure having sides notched to receive said axle sothat the sides may extend below the axle when the figure is tilted.

4. In a toy figure comprising a. wheeled frame and a figure. movable inrelation to the frame, said frame having wheels at the front and rear onwhich the toy figure is moved along; the rear wheels being secured to anaxle supporting the rear of the figure and provided with cams secured torotate with the rear wheels and provided with oblique cam faces forengaging substantially parallel faces on said figure to tilt and-Swingthe figure in relation to the. frame, means on said frame supporting thefront endof said figure to permit the front end to swing from sideinside in relation to said frame while tilting to impart a waddlingmotion to said figure, said cams engaging the parallel sides of a centerboss in said object to; tilt and swing'saidobject in relation to theframe.
